Radius of an aluminum atom

Of aluminium isotopes, only Al is stable. This situation is common for elements with an odd atomic number. It is the only primordial aluminium isotope, i.e. the only one that has existed on Earth in its current form since the formation of the planet. Nearly all aluminium on Earth is present as this isotope, which makes it a mononuclidic element and means that its standard atomic weight is virtually th… WebA more current estimate of the size of the aluminum nucleus can be obtained by subsituting the mass number of aluminum (A=27) into the nuclear radius relationship. That gives a nuclear radius of 3.6 fm for aluminum.
